Table 3 Results of multiple logistical regression: Odds ratio for a positive QFT-G (QFT-Gold) result

From: Tuberculosis contact investigation with a new, specific blood test in a low-incidence population containing a high proportion of BCG-vaccinated persons

QFT-G Odds ratio 95% confidence interval p
BCG vaccination 0.7 0.3–1.4 0.29 (n.s.)
Age 1.0 0.98–1.1 0.5 (n.s.)
Sex 1.4 0.6–3.2 0.4 (n.s.)
Origin (Foreign/German) 4.7 2.1–10.5 <0.0001
Previous contact tracing 3.9 0.6–24.1 0.1 (n.s.)
Exposure time 1.0 0.99–1.0 0.8 (n.s.)
